Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of loose fiber dyeing, in particular to an intelligent unmanned dyeing device based on reactive dyes and a dyeing process thereof. BACKGROUND

[0002] The rough combing wool and silk, cotton and viscose blended products are dyed by loose wool dyeing method, and the wool and silk, cotton and viscose are dyed respectively. The loose wool dyeing machine mainly processes loose fibers that have not been formed into yarn. The structure of the loose wool dyeing machine is usually made of stainless steel and is equipped with a circulating pump, a porous pipe and other components. The working principle of the loose wool dyeing machine is to realize uniform penetration of fibers inside and outside by forced circulation of dyeing liquid. First, the loose fibers are evenly filled into the inner cylinder with holes, and then the fibers are compacted by an automatic compacting device. The dyeing liquid is driven by the circulating pump, extracted from the dyeing tank, injected into the inner cylinder through the porous pipe, penetrates the fiber layer from the inner cylinder wall, and then returns to the dyeing tank to form a closed circulation. During dyeing, the steam heating system is used to gradually increase the temperature to promote the combination of dye molecules and fibers and further accelerate the dyeing reaction. The temperature and pump speed are adjusted in real time by an intelligent control system to ensure process stability. When the fiber raw materials are put into the inner cylinder, the volume and weight of the fiber raw materials cannot be in a fixed ratio due to their certain bulkiness. After the fiber raw materials are put into the inner cylinder to a certain height, the density of the fiber raw materials at different positions may differ, which may cause uneven feeding at different positions in the inner cylinder. During the compaction of the raw materials, the compacting block may press the upper surface of the fiber raw materials to the same height, so that the raw materials may be compacted too tightly at the places with more raw materials, while the raw materials may be relatively loose at the places with less raw materials. During the penetration of the dyeing liquid, the penetration may be uneven, which may cause uneven dyeing of the fiber raw materials. Therefore, we propose an intelligent unmanned dyeing device based on reactive dyes and a dyeing process thereof. SUMMARY

when the inner cylinder 8 does not tilt, the magnetic plate 10 is located at the middle position in the dye vat 1, there is a certain distance between the magnetic plate 10 and the magnetic block 31, the magnetic attraction generated therebetween is small and is insufficient to overcome the elastic force of the second spring 30 and the elastic rod 32, so the magnetic block 31 does not slide in the push plate 25, when the inner cylinder 8 tilts due to uneven feeding of the raw material, the magnetic plate 10 tilts to the side with more raw material, the push plate 25 approaches and then moves away from the magnetic plate 10 during rotation, the magnetic attraction between the magnetic block 31 and the magnetic plate 10 increases during the approach of the push plate 25 and the magnetic

[0020] The lower end of the rotating disc 21 is also fixedly provided with two fixed rods 33, the lower end of each fixed rod 33 is vertically slidably provided with a pressing block 34 for extruding the fiber raw material, the lower end of the limiting ring 37 is fixedly provided with a plurality of first hemispherical blocks 38 arranged in a circle, the upper end of each pressing block 34 is fixedly provided with a second hemispherical block 39 matched with the first hemispherical block 38, and the upper end of each pressing block 34 is fixedly connected with the rotating disc 21 through a third spring 35, the two pressing blocks 34 are alternately pressed downward, during the extension of the air cylinder 36, the second hemispherical block 39 is limited by the limiting ring 37 and the first hemispherical block 38, so as to drive the two pressing blocks 34 to move downward to a suitable height, and the third spring 35 is correspondingly stretched, at the same time, during the rotation of the rotating disc 21, the fixed rod 33, the pressing block 34 and the second hemispherical block 39 are synchronously rotated, the elastic force of the third spring 35 always drives the second hemispherical block 39 to adhere to the surface of the first hemispherical block 38 and the limiting ring 37, when the second hemispherical block 39 contacts with the first hemispherical block 38, the second hemispherical block 39 will first move downward along the surface of the first hemispherical block 38, and then move upward to reset, so that the pressing block 34 performs one-time up-down movement, with the second hemispherical block 39 continuously contacting with the first hemispherical block 38, the pressing block 34 will continuously perform up-down reciprocating movement, and as shown in the attached Figure 11 figure, there is a certain angle difference between the two pressing blocks 34, when one second hemispherical block 39 contacts with the first hemispherical block 38, the other second hemispherical block 39 will move to between the two first hemispherical blocks 38, so that the two pressing blocks 34 alternately perform up-down reciprocating movement, and continuously press the fiber raw material.

[0021] A plurality of shunt pipes 16 are arranged in the porous pipe 6, a flow channel 17 for dye liquid is arranged between every two shunt pipes 16, the liquid outlet holes 7 are arranged in a multi-layer annular arrangement, the flow channels 17 and the liquid outlet holes 7 are layer by layer corresponding and connected, the liquid passing area of each flow channel 17 is the same, each liquid outlet hole 7 is arranged in a funnel shape with the outside small and the inside large, and the diameter of the liquid outlet hole 7 in the inner wall of the porous pipe 6 increases from bottom to top, the dye liquid is shunted through the shunt pipe 16, the liquid passing area of each flow channel 17 is the same, the amount of dye liquid in each flow channel 17 is the same, and the amount of liquid outlet of each layer of liquid outlet holes 7 is also consistent, preventing the dyeing from being uneven due to the small amount of dye liquid outlet at the upper end of the porous pipe 6, at the same time, since the porous pipe 6 is arranged in a tapered shape with the lower end wide and the upper end narrow, and the liquid outlet holes 7 are arranged in a funnel shape with the outside small and the inside large, the pressure of the dye liquid can be increased, and it is ensured that the dye liquid passes through the fiber and is discharged from the hole on the wall of the inner cylinder 8, since the fixed strip 9 is arranged in an inclined manner, the storage capacity of the fiber in the inner cylinder 8 increases from bottom to top, and the diameter of the liquid outlet hole 7 in the inner wall of the porous pipe 6 increases from bottom to top, so that the liquid outlet pressure of the liquid outlet hole 7 also increases from bottom to top, and it is ensured that the pressure of the dye liquid sprayed from the upper end liquid outlet hole 7 is enough to pass through the fiber, and the consistency of dyeing is improved.

[0022] Specifically, first, the porous tube 6 is aligned with the position between the plurality of fixed strips 9, and then the positioning block 14 is aligned with the positioning groove 15. After that, the inner cylinder 8 is placed on the supporting ring 11, and the inner cylinder 8 is balanced by its own gravity and will not tilt. After the raw materials are gradually put into the inner cylinder 8, uneven raw material feeding will cause the inner cylinder 8 to be unevenly stressed. The first spring 12 on the side with more raw materials will be compressed more, and the inner cylinder 8 will tilt with the supporting ring 11. When the raw materials are not fed, the first spring 12 will not be compressed to the lowest point, the fixed strip 9 will not stick to the outer wall of the porous tube 6, and the inner cylinder 8 will not be limited by the porous tube 6. The inner cylinder 8 will always tilt to the side with more raw materials. During the feeding of the fiber raw materials, the rotating frame 19 is rotated above the inner cylinder 8. According to the amount of raw materials and the pressure required by different raw materials, the extension amount of the cylinder 36 is adjusted, the cylinder 36 drives the limiting ring 37 to move downward, and the push plate 25 is driven to move to the appropriate height. Then the motor 20 will start and drive the rotating disc 21 to rotate, and the push plate 25 will rotate synchronously with the rotating disc 21. The water flows into the sleeve 23 through the water pipe 22 and is discharged into the inner cylinder 8 through the water outlet hole 26, which can wet the fiber raw materials and facilitate the compression of the fiber raw materials. When the inner cylinder 8 tilts due to uneven raw material feeding, the magnetic plate 10 tilts to the side with more raw materials. During the rotation of the push plate 25, the push plate 25 will first approach and then move away from the magnetic plate 10. During the approach of the push plate 25 and the magnetic plate 10, the magnetic attraction between the magnetic block 31 and the magnetic plate 10 increases continuously. The magnetic block 31 will be pulled by the magnetic attraction to move towards the magnetic plate 10. The end of the magnetic block 31 will cooperate with the wedge block 29 to push the wedge block 29 and the fixed block 28 and the slide rod 27 downward. The slide rod 27 will be inserted into the fiber raw materials and will pull the excess fiber raw materials to move along the inner cylinder 8 during the rotation of the push plate 25. Then the distance between the magnetic block 31 and the magnetic plate 10 will gradually increase, and the magnetic attraction on the magnetic block 31 will gradually decrease. The second spring 30 and the elastic rod 32 will gradually reset the magnetic block 31 and the slide rod 27. The excess fiber raw materials will be gradually distributed to the side with less fiber as the slide rod 27 retracts. With the continuous rotation of the push plate 25, the excess fiber raw materials are continuously distributed, making the fiber raw materials more evenly distributed, and the stress on the inner cylinder 8 gradually recovers. During the extension of the cylinder 36, the two pressing blocks 34 are driven to move downward to the appropriate height, and the third spring 35 is correspondingly stretched. At the same time, during the rotation of the rotating disc 21, the fixed rod 33, the pressing block 34, and the second hemisphere block 39 are synchronously rotated. When the second hemisphere block 39 contacts the first hemisphere block 38, the second hemisphere block 39 will first move downward along the surface of the first hemisphere block 38 and then move upward to reset, so that the pressing block 34 moves up and down once. With the continuous contact between the second hemisphere block 39 and the first hemisphere block 38, the pressing block 34 will continuously move up and down. When one second hemisphere block 39 contacts the first hemisphere block 38, the other second hemisphere block 39 will move between the two first hemisphere blocks 38, so that the two pressing blocks 34 move up and down alternately and continuously compress the fiber raw materials.After the fiber raw material is compressed, the rotating frame 19 is rotated, and then the upper cover of the dye vat 1 is closed. A certain amount of dye is added to the dye cylinder 3. The dyeing parameters are set. The dye vat 1 is heated and pressurized to the appropriate range. The circulating pump 2 draws the dye solution in the dye vat 1 from the dye solution tank 5 and inputs it into the multi-hole pipe 6. The dye solution is divided by the shunt pipe 16. The amount of dye solution in each flow channel 17 is the same. The amount of liquid discharged from each layer of liquid outlet hole 7 is also consistent. The liquid outlet hole 7 can increase the dye pressure. The inner cylinder 8 gradually increases the fiber capacity from bottom to top. The liquid outlet pressure of the liquid outlet hole 7 from bottom to top also increases accordingly. It is ensured that the dye pressure sprayed from the upper end of the liquid outlet hole 7 is sufficient to penetrate the fiber and be discharged from the holes on the wall of the inner cylinder 8.

[0023] A dyeing process of an intelligent unmanned dyeing device based on reactive dyes, specifically comprising the following steps: S1, place the inner cylinder 8 on the supporting ring 11 in the dye vat 1. Select appropriate fiber raw materials and reactive dyes, and put the reactive dyes into the dye cylinder 3. S2, rotate the rotating frame 19 above the inner cylinder 8. According to the amount of fiber raw material and the required pressure, adjust the extension amount of the air cylinder 36. Start the motor 20 to drive the rotating disc 21 and the push plate 25 to rotate synchronously. Water flows through the water pipe 22 into the sleeve 23, and is discharged into the inner cylinder 8 through the water outlet hole 26 on the push plate, wetting the fiber raw material. The inner cylinder 8 drives the magnetic plate 10 to tilt towards the side with more raw materials. The push plate 25 approaches the magnetic plate 10 during rotation. The magnetic block 31 is pulled towards the magnetic plate 10 by magnetic force. The slide rod 27 is inserted into the fiber raw material and pulls the excess raw material to move in a circular motion along the inner cylinder 8. As the push plate 25 continues to rotate, the magnetic force on the magnetic block 31 decreases, and the slide rod 27 gradually returns to its original position. The excess fiber raw material is distributed to the side with less fiber. S3, the rotating disc 21 drives the fixed rod 33, the pressing block 34 and the second half block 39 to rotate synchronously. When the second half block 39 contacts the first half block 38, it first moves downward along the surface of the first half block 38 and then returns to its original position, causing the pressing block 34 to move up and down once. The two pressing blocks 34 have an angle difference, allowing them to move up and down alternately and repeatedly, constantly compressing the fiber raw material. S4, after the fiber raw material is compressed, rotate the rotating frame 19 to the initial position, close the upper cover of the dye vat 1, set the dyeing parameters according to the process requirements, start the circulating pump 2 to draw the dye solution in the dye vat 1 from the dye solution tank 5 and input it into the multi-hole pipe 6. The dye solution is divided by the shunt pipe 16. Ensure that the amount of dye solution in each flow channel 17 is the same. The amount of liquid discharged from each layer of liquid outlet hole 7 is consistent. The liquid outlet pressure of the liquid outlet hole 7 from bottom to top also increases accordingly. It is ensured that the dye pressure sprayed from the upper end of the liquid outlet hole 7 is sufficient to penetrate the fiber, and be discharged from the holes on the wall of the inner cylinder 8. S5, heat and pressurize the dye vat 1 to the set range to promote the combination of dye molecules and fibers. Real-time monitoring and adjustment of temperature, pump speed and other parameters ensure the stability and consistency of the dyeing process. S6, after reaching the predetermined dyeing time, stop the circulating pump 2 and the heating system, let the dyeing solution cool naturally or perform rapid cooling according to process requirements, open the upper cover of the dye vat 1, take out the inner cylinder 8 and the fiber raw material after dyeing.

A dyeing process for an intelligent unmanned dyeing device based on reactive dyes, characterized in that: The dyeing process using the intelligent unmanned dyeing device based on reactive dyes as described in claim 9 specifically includes the following steps: S1. Place the inner cylinder (8) on the support ring (11) inside the dyeing vat (1), select suitable fiber raw materials and reactive dyes, and put the reactive dyes into the dye cylinder (3); S2. Rotate the rotating frame (19) above the inner cylinder (8). Adjust the extension of the cylinder (36) according to the amount of fiber raw material and the required pressure. Start the motor (20) to drive the turntable (21) and push plate (25) to rotate synchronously. Water flows into the sleeve (23) through the water pipe (22) and is discharged into the inner cylinder (8) through the water outlet (26) on the push plate to wet the fiber raw material. The inner cylinder (8) drives the magnetic plate (10) to tilt towards the side with more raw material. The push plate (25) approaches the magnetic plate (10) during rotation. The magnetic block (31) is pulled towards the magnetic plate (10) by the magnetic attraction force. The slide rod (27) is inserted into the raw material fiber and pulls the excess raw material to move in a circle along the inner cylinder (8).

There is an angle difference between the two pressure blocks (34), so that they can alternate up and down reciprocating motion and continuously press the fiber raw material. S4. After the fiber raw material is pressed, rotate the rotating frame (19) to the initial position, close the top cover of the dyeing tank (1), set the dyeing parameters according to the process requirements, start the circulation pump (2), and draw the dye liquid in the dyeing tank (1) out of the dyeing tank (5) and input it into the porous pipe (6).

S5. Heat and pressurize the dyeing vat (1) to the set range to promote the combination of dye molecules and fibers. Monitor and adjust parameters such as temperature and pump speed in real time to ensure the stability and consistency of the dyeing process. S6.
